Fred Drake 49b0c3bafe Fix bug #392, reported by Jonathan Giddy <jon@dstc.edu.au>:
In posixmodule.c:posix_fork, the function PyOS_AfterFork is called for
both the parent and the child, despite the docs stating that it should
be called in the new (child) process.

This causes problems in the parent since the forking thread becomes the
main thread according to the signal module.

Calling PyOS_AfterFork() only in the child fixes this.  Changed for both
fork() and forkpty().

Fred Drake 7bd9f41c65 pyexpat.errors is a *strange* module!
It gets initialized when pyexpat is imported, and is only accessible as an
attribute of pyexpat; it cannot be imported itself.  This allows it to at
least be importable after pyexpat itself has been imported by adding it
to sys.modules, so it is not quite as strange.

This arrangement needs to be better thought out.

Guido van Rossum 9f754e0e2d In b_setitem(), instead of the platform dependent CHAR_MIN and
CHAR_MAX, use hardcoded -128 and 127.  This may seem strange, unless
you realize that we're talking about signed bytes here!  Bytes are
always 8 bits and 2's complement.  CHAR_MIN and CHAR_MAX are
properties of the char data type, which is guaranteed to hold at least
8 bits anyway.

Otherwise you'd get failing tests on platforms where unsigned char is
the default (e.g. AIX).

Thanks, Vladimir Marangozov, for finding this nit!

Fred Drake a44d353e2b Trent Mick <trentm@activestate.com>:
The common technique for printing out a pointer has been to cast to a long
and use the "%lx" printf modifier. This is incorrect on Win64 where casting
to a long truncates the pointer. The "%p" formatter should be used instead.

The problem as stated by Tim:
> Unfortunately, the C committee refused to define what %p conversion "looks
> like" -- they explicitly allowed it to be implementation-defined. Older
> versions of Microsoft C even stuck a colon in the middle of the address (in
> the days of segment+offset addressing)!

The result is that the hex value of a pointer will maybe/maybe not have a 0x
prepended to it.


Notes on the patch:

There are two main classes of changes:
- in the various repr() functions that print out pointers
- debugging printf's in the various thread_*.h files (these are why the
patch is large)


Closes SourceForge patch #100505.

Fredrik Lundh 0640e1161f the mad patcher strikes again:
-- added pickling support (only works if sre is imported)

-- fixed wordsize problems in engine
   (instead of casting literals down to the character size,
   cast characters up to the literal size (same as the code
   word size).  this prevents false hits when you're matching
   a unicode pattern against an 8-bit string. (unfortunately,
   this broke another test, but I think the test should be
   changed in this case; more on that on python-dev)

-- added sre.purge function
   (unofficial, clears the cache)

Fred Drake a04eaad5c7 Trent Mick <trentm@activestate.com>:
This patch fixes possible overflows in the socket module for 64-bit
platforms (mainly Win64). The changes are:

- abstract the socket type to SOCKET_T (this is SOCKET on Windows, int
on Un*x), this is necessary because sizeof(SOCKET) > sizeof(int) on
Win64

- use INVALID_SOCKET on Win32/64 for an error return value for
accept()

- ensure no overflow of the socket variable for: (1) a PyObject return
value (use PyLong_FromLongLong if necessary); and (2) printf
formatting in repr().

Closes SourceForge patch #100516.

Guido van Rossum f385c5e544 Patch by Nadav Horesh to make acosh and asinh better.
Tim posted a long comment to python-dev (subject: "Controversial patch
(cmath)"; date: 6/29/00).  The conclusion is that this whole module
stinks and this patch isn't perfect, but it's better than the acosh
and asinh we had, so let's check it in.

Fredrik Lundh 29c08beab0 still trying to figure out how to fix the remaining
group reset problem.  in the meantime, I added some
optimizations:

- added "inline" directive to LOCAL

  (this assumes that AC_C_INLINE does what it's
  supposed to do).  to compile SRE on a non-unix
  platform that doesn't support inline, you have
  to add a "#define inline" somewhere...

- added code to generate a SRE_OP_INFO primitive

- added code to do fast prefix search

  (enabled by the USE_FAST_SEARCH define; default
  is on, in this release)

Fred Drake 0e12395190 Trent Mick <trentm@activestate.com>:
This patch fixes a possible overflow in the Sleep system call on
Win32/64 in the time_sleep() function in the time module. For very
large values of the give time to sleep the number of milliseconds can
overflow and give unexpected sleep intervals. THis patch raises an
OverflowError if the value overflows.

2000-06-29 21:31:02 +00:00
Fred Drake 699f352fb2 Trent Mick <trentm@activestate.com>:
This patch fixes the posix module for large file support mainly on
Win64, although some general cleanup is done as well.

The changes are:

- abstract stat->STAT, fstat->FSTAT, and struct stat->STRUCT_STAT
This is because stat() etc. are not the correct functions to use on
Win64 (nor maybe on other platforms?, if not then it is now trivial to
select the appropriate one). On Win64 the appropriate system functions
are _stati64(), etc.

- add _pystat_fromstructstat(), it builds the return tuple for the
fstat system call. This functionality was being duplicated. As well
the construction of the tuple was modified to ensure no overflow of
the time_t elements (sizeof(time_t) > sizeof(long) on Win64).

- add overflow protection for the return values of posix_spawnv and
posix_spawnve

- use the proper 64-bit capable lseek() on Win64

- use intptr_t instead of long where appropriate from Win32/64 blocks
(sizeof(void*) > sizeof(long) on Win64)

This closes SourceForge patch #100513.

Fred Drake dfb4ebda24 Trent Mick <trentm@activestate.com>:
Mark Hammond provided (a long time ago) a better Win32 specific
time_clock implementation in timemodule.c. The library for this

makes Win64 fall back on the system's clock() function for
time_clock().

Fredrik Lundh be2211e940 - fixed split

Fix warnings on 64-bit build build of signalmodule.c

effective change.)

Guido van Rossum 3262e16753 Trent Mick:
This patches fixes a possible overflow of the optional timeout
parameter for the select() function (selectmodule.c). This timeout is
passed in as a double and then truncated to an int. If the double is
sufficiently large you can get unexpected results as it
overflows. This patch raises an overflow if the given select timeout
overflows.

[GvR: To my embarrassment, the original code was assuming an int could
always hold a million.  Note that the overflow check doesn't test for
a very large *negative* timeout passed in -- but who in the world
would do such a thing?]

Guido van Rossum 40ced50cb0 Jack Jansen: Mac Carbon: don't include sys/types if we don't have it 2000-06-28 20:56:30 +00:00
Fred Drake 541dc3b7b2 Trent Mick <trentm@activestate.com>:
The cause: Relatively recent (last month) patches to getargs.c added
overflow checking to the PyArg_Parse*() integral formatters thereby
restricting 'b' to unsigned char value and 'h','i', and 'l' to signed
integral values (i.e. if the incoming value is outside of the
specified bounds you get an OverflowError, previous it silently
overflowed).

The problem: This broke the array module (as Fredrik pointed out)
because *its* formatters relied on the loose allowance of signed and
unsigned ranges being able to pass through PyArg_Parse*()'s
formatters.

The fix: This patch fixes the array module to work with the more
strict bounds checking now in PyArg_Parse*().

How: If the type signature of a formatter in the arraymodule exactly
matches one in PyArg_Parse*(), then use that directly. If there is no
equivalent type signature in PyArg_Parse*() (e.g. there is no unsigned
int formatter in PyArg_Parse*()), then use the next one up and do some
extra bounds checking in the array module.

This partially closes SourceForge patch #100506.

Lib/pty.py is also rewritten to use openpty when available, but falls
back to the old SGI method or the "manual" BSD open-a-pty
code. Openpty() is necessary to use the Unix98 ptys under Linux 2.2,
or when using non-standard tty names under (at least) BSDI, which is
why I needed it, myself ;-) forkpty() is included for symmetry.

Jeremy Hylton 847a9968e9 Patch from M.-A. Lemburg:
Python on UNIX now trusts PYTHONHOME unconditionally

Modules/getpath.c:

Landmark changed to os.py.

Setting PYTHONHOME now unconditionally sets sys.prefix
(and sys.exec_prefix). No further checks are done whether the
standard lib can be found in that location or not. This is in
sync with the PC subdir getpath implementations.

PC/getpathp.c:

Landmark changed to os.py.

PC/os2vacpp/getpathp.c:

Landmark changed to os.py.

Note: BAW's checkin on exceptions.c eliminates earlier concerns about
a bogus PYTHONHOME value leading to a core dump.  Instead it causes a
useless sys.path and prevents imports.

Guido van Rossum c9a5f343bc The addition of rint() (by Peter Schneider-Kamp; I forgot to mention

Guido van Rossum ea2b7157ab New version from Jim Fulton to fix a problem that Eric Raymond ran
into.  Jim writes:

The core dump was due to a C decrement operation
in a macro invocation in load_pop.  (BAD)

I fixed this by moving the decrement outside
the macro call.

I added a comment to load_pop and load_mark
to document the fact that cPickle separates the
unpickling stack into two separate stacks, one for
objects and one for marks.

I also moved some increments out of some macro
calls (PyTuple_SET_ITEM and PyList_SET_ITEM).
This wasn't necessary, but made me feel better. :)

I tested these changes in *my* cPickle, which
doesn't have the new Unicode stuff.
2000-05-09 18:14:50 +00:00
Guido van Rossum c554505ca1 Trent Mick:
Fix overflow bug in ldexp(x, exp). The 'exp' argument maps to a C int for the
math library call [double ldexp(double, int)], however the 'd'
PyArg_ParseTuple formatter was used to yield a double, which was subsequently
cast to an int. This could overflow.

[GvR: mysteriously, on Solaris 2.7, ldexp(1, 2147483647) returns Inf
while ldexp(1, 2147483646) raises OverflowError; this seems a bug in
the math library (it also takes a real long time to compute the
Inf outcome).  Does this point to a bug in the CHECK() macro?  It
should have discovered that the result was outside the HUGE_VAL range.]
2000-05-08 14:29:38 +00:00
Guido van Rossum 69529ad0cc When the UTF-8 conversion to Unicode fails, return an 8-bit string
instead.  This seems more robust than returning an Unicode string with
some unconverted charcters in it.

This still doesn't support getting truly binary data out of Tcl, since
we look for the trailing null byte; but the old (pre-Unicode) code did
this too, so apparently there's no need.  (Plus, I really don't feel
like finding out how Tcl deals with this in each version.)
2000-05-04 15:55:17 +00:00
Guido van Rossum 990f5c6c98 Two changes to improve (I hope) Unicode support.
1. In Tcl 8.2 and later, use Tcl_NewUnicodeObj() when passing a Python
Unicode object rather than going through UTF-8.  (This function
doesn't exist in Tcl 8.1, so there the original UTF-8 code is still
used; in Tcl 8.0 there is no support for Unicode.)  This assumes that
Tcl_UniChar is the same thing as Py_UNICODE; a run-time error is
issued if this is not the case.

2. In Tcl 8.1 and later (i.e., whenever Tcl supports Unicode), when a
string returned from Tcl contains bytes with the top bit set, we
assume it is encoded in UTF-8, and decode it into a Unicode string
object.

Notes:

- Passing Unicode strings to Tcl 8.0 does not do the right thing; this
isn't worth fixing.

- When passing an 8-bit string to Tcl 8.1 or later that has bytes with
the top bit set, Tcl tries to interpret it as UTF-8; it seems to fall
back on Latin-1 for non-UTF-8 bytes.  I'm not sure what to do about
this besides telling the user to disambiguate such strings by
converting them to Unicode (forcing the user to be explicit about the
encoding).

- Obviously it won't be possible to get binary data out of Tk this
way.  Do we need that ability?  How to do it?

Guido van Rossum 19dde103a8 Mark Hammond to the rescue:
Checkin 2.131 of posixmodule.c changed os.stat on Windows, so that
"/bin/" type notation (trailing backslash) would work on Windows to
be consistent with Unix.

However, the patch broke the simple case of: os.stat("\\")

This did work in 1.5.2, and obviously should!

This patch addresses this, and restores the correct behaviour.

Guido van Rossum 7d64b48eaf Disable the ZEROTRAP code -- this turns a 0 byte into a 2 byte and I

Guido van Rossum ff3ab42c04 Jack Jansen: The GUSI 2.0 I/O library used on the Mac uses the
socklen_t (unsigned int) for most size parameters.  Apparently this is
part of the UNIX 98 standard.

[GvR: the changes to configure.in etc. that I just checked in make
sure that socklen_t is defined everywhere, so I deleted the little
part of Jack's mod to define socklen_t if not in GUSI2.  I suppose I
will have to add it to the Windows config.h in a minute.]
